    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jiale Deng; [2023]
    Nyckelord :Three-level inverters; over-modulation techniques; space vector modulation; neutral-point voltage balancing; non-uniform Fourier transform; Trenivåväxelriktare; övermodulation; spacevektormodulering; balansering av nollpunktsspänning; olikformig Fouriertransform;

    Sammanfattning : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. LÄS MER

  2. 2. SIGNALBEHANDLING MED AVANCERAD BLUETOOTH-TEKNIK OCH OPTIMERADE OPERATIVSYSTEM : Optimera audiosystemet i ett avancerat inbyggt system med en fler-trådad programvara och synkroniserings mekanism

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Omar Ibrahim; [2023]
    Nyckelord :BM83 bluetooth; audio subsystem; Inter-IC sound; Digital Signal Processor; Operative System; DSP platform tests.;

    Sammanfattning : This study is about replacing an old bluetooth module with a new variant, namely the BM83 which is an integrated circuit that contains an internal DSP circuit, profiles and important functions such as noise reduction, acoustic echo removal and EQ filtering. The purpose of this study is to replace the old module with the BM83, as well as explore the internal DSP circuit in the BM83. LÄS MER

    Sammanfattning : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. LÄS MER

  4. 4. Fast Classification of Obfuscated Malware with an Artificial Neural Network

    Kandidat-uppsats, KTH/Datavetenskap

    Författare :Johan Luhr; Hannes Hallqvist; [2022]
    Nyckelord :;

    Sammanfattning : Malware has posed a problem ever since the first variant was created in the 1980s. As malware detection techniques have advanced, malware developers have in turn found better ways to hide and obfuscate malware. Machine learning (ML) has seen great expansion into many fields over the last years, this includes the field of cybersecurity. LÄS MER

  5. 5. Comparison of Distance Metrics for Trace Clustering in Process Mining : An Effort to Simplify Analysis of Usage Patterns in PACS

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Christoffer Sjöbergsson; [2022]
    Nyckelord :Trace Clustering; Process Mining; User behavior classification;

    Sammanfattning : This study intended to validate if clustering could be used to simplify models generated with process mining. The intention was also to see if these clusters could suggest anything about user efficiency. To that end a new metric where devised, average mean duration deviation. LÄS MER
